ABSTRACT
Quaternary ammonium glucosamine conjugatewas prepared by a two step procedure.First,condensation of glucosamine hydrochloride with chloro acetic chloride in the presence of potassium bicarbonate in aqueous medium at 0℃ provided the N chloroacetyl derivative in 74% yield.Subsequent reaction of this intermediate with pyridine at 40℃ for 3 days gave the pyridinium conjugate in 71% yield.The structures of compounds were confirmed by IR,NMR spectra and element analysis.
